    Default [QT3] QComboBox: Disable adding items on Enter-keypress (solved)

    Hello

    I have a question.

    Is it possible to disable the function of a editable QComboBox to add items on a Enter-keypress ?

    see the screenshot, I don't want item1 to be added to the list when Enter is pressed.


    Thx in advance

    Install an event filter on it and filter out the return and enter keys.

    So it means I have to subclass QComboBox (e.g MyComboBox) and override keyPressEvent by adding it to MyComboBox?


    edit: thx wysota, you solved my problem

    No, you have to apply an "eventFilter" (installEventFilter() and eventFilter()).

    Thx! I will try it out on Monday at my work, didn't realize that you meant this..
    The subclassing method worked also, but your solution looks better

    It's not "better". It's "quicker" and "simpler"

    May be you should try method setInsertionPolicy( QComboBox::NoInsertion).
